Hi @leondz

if that is still up for grabs I'd like to submit a pull request - unless it is already actively worked on.

@mhupfauer hi! yes please, that sounds great.

• here's another community probe doing this kind of thing: https://github.com/NVIDIA/garak/blob/main/garak/probes/visual_jailbreak.py
• if it's possible to code this probe with QRs having customisable text, that would be outstanding
